What is the OPITO Helideck Assistant course?
Working on an offshore helideck is a high-responsibility role that requires specific training and certification. Whether you are new to helideck operations or looking to understand what the qualification involves, this guide answers the most common questions about the OPITO Helideck Assistant course in a clear and practical way.
What is the OPITO Helideck Assistant course?
The OPITO Helideck Assistant (HDA) course is a certified training programme that prepares personnel to safely assist with helicopter operations on offshore installations. It covers the knowledge and practical skills needed to support helideck operations, including firefighting, emergency response, and helicopter marshalling, all in line with OPITO standards.
The course is designed specifically for the offshore environment, where helicopter transport is a routine but safety-critical activity. Helidecks on platforms and vessels operate under strict safety protocols, and the Helideck Assistant plays a key role in ensuring those operations run without incident. The training combines theoretical instruction with hands-on practical exercises, giving participants direct experience of the scenarios they will encounter on the job.
OPITO, the global skills body for the energy sector, sets the standards for this certification, which is widely recognised across the offshore oil and gas industry.
Who needs to complete the Helideck Assistant training?
The Helideck Assistant course is required for any personnel who are designated to assist with helicopter operations on offshore installations. This typically includes crew members assigned to helideck duties, emergency response team members, and anyone whose role involves supporting helicopter arrivals and departures on a platform or vessel.
Employers in the offshore oil and gas sector are required to ensure that helideck teams are properly trained and certified. This means that if your role involves marshalling aircraft, operating firefighting equipment on the helideck, or participating in emergency drills related to helicopter operations, the HDA certification is mandatory.
The course is also relevant for personnel transitioning into helideck roles from other positions on an installation, as well as for those refreshing their knowledge after a period away from active helideck duties.
What topics are covered in the OPITO HDA course?
The OPITO HDA training covers all the core competencies needed to perform safely and effectively as a Helideck Assistant. The curriculum is structured to build both theoretical understanding and practical confidence.
- Helideck operations and safety management
- Roles and responsibilities of the Helideck Assistant
- Helicopter types, terminology, and hazard awareness
- Firefighting equipment and firefighting techniques specific to helideck environments
- Emergency response procedures, including crash rescue and evacuation
- Marshalling signals and communication with flight crew
- Personal protective equipment (PPE) for helideck operations
- Fuel hazards and hot refuelling procedures
The practical elements of the course are particularly important. Participants take part in simulated emergency scenarios that replicate real helideck conditions, ensuring they are prepared to act quickly and correctly under pressure. This combination of classroom learning and hands-on practice is what makes the helideck safety training both credible and effective.
How long does the Helideck Assistant course take to complete?
The OPITO Helideck Assistant course typically takes three to four days to complete. The exact duration can vary slightly depending on the training provider and the specific programme structure, but the course is designed to be intensive and focused, covering both theoretical and practical content within that timeframe.
Because the training includes hands-on exercises and simulated emergency scenarios, participants should expect full days of active participation rather than passive classroom sessions. Scheduling the course close to a project start date is a practical approach, and many professionals choose a training centre near an airport or port to make travel logistics straightforward. Contact us to find out about available course dates and locations to plan your training around your travel or project schedule.
How long is an OPITO Helideck Assistant certificate valid?
An OPITO Helideck Assistant certificate is valid for four years from the date of issue. After this period, certified personnel are required to complete a refresher or renewal course to maintain their certification and continue working in helideck roles.
Keeping your certification current is important not only for compliance but also for staying up to date with any changes in helideck safety procedures and OPITO standards. Employers in the offshore sector routinely verify the validity of HDA certificates before assigning personnel to helideck duties, so it is worth planning your renewal well in advance of the expiry date.
If you hold other OPITO offshore courses, it is worth aligning renewal dates where possible to reduce time away from work.
Where can you take the OPITO Helideck Assistant course?
The OPITO Helideck Assistant course is available at OPITO-approved training centres around the world. Locations are typically chosen to serve the offshore industry, meaning you will often find training facilities near major ports, airports, or energy sector hubs.
When choosing a provider, look for a centre that holds full OPITO approval, employs instructors with practical offshore experience, and offers flexible scheduling to fit around your project commitments. Proximity to your departure point for an offshore assignment is also worth considering, as many professionals complete their training immediately before travelling to a platform or vessel.

Frequently Asked Questions
Do I need any prior experience or qualifications before taking the OPITO Helideck Assistant course?
There are no formal academic prerequisites for the OPITO Helideck Assistant course, but candidates are generally expected to be employed in or transitioning into an offshore role that involves helideck duties. Most providers will require you to meet basic offshore medical fitness standards, such as holding a valid ENG1 or equivalent medical certificate, before attending. If you are unsure whether your current qualifications or fitness certificates are sufficient, it is worth confirming directly with your training provider before booking.
What is the difference between a Helideck Assistant and a Helideck Landing Officer (HLO)?
The Helideck Assistant (HDA) supports helicopter operations under supervision, handling tasks such as firefighting standby, marshalling, and emergency response. The Helideck Landing Officer (HLO) holds a higher-level certification and takes overall responsibility for the safe management of helideck operations, including final authority over aircraft movements. If you are starting out in helideck operations, the HDA certification is the appropriate entry point, with the HLO qualification available as a natural progression once you have gained practical on-deck experience.
What happens if I fail an assessment during the OPITO Helideck Assistant course?
OPITO-approved courses include both theoretical assessments and practical evaluations, and most providers allow a reassessment opportunity if a participant does not meet the required standard on the first attempt. The specific reassessment policy can vary between training centres, so it is worth asking your provider about their process before the course begins. If you do not achieve certification, you will typically need to repeat the relevant elements of the training rather than the full course, depending on where the gap in performance occurred.
Can I complete the OPITO Helideck Assistant course if I already hold other offshore safety certifications like BOSIET or FOET?
Yes, holding certifications such as BOSIET (Basic Offshore Safety Induction and Emergency Training) or FOET (Further Offshore Emergency Training) is entirely compatible with taking the HDA course, and in practice many offshore professionals hold multiple OPITO qualifications simultaneously. These certifications cover different competency areas, so there is no overlap that would exempt you from HDA training. Aligning your renewal dates across multiple OPITO certificates is a practical way to minimise time away from work and simplify your compliance management.
Is the OPITO Helideck Assistant certification recognised internationally, or only in specific regions?
The OPITO HDA certification is internationally recognised and accepted across the global offshore oil and gas industry, including major operating regions such as the North Sea, the Gulf of Mexico, West Africa, the Middle East, and Southeast Asia. Because OPITO is the global skills body for the energy sector, its standards are applied consistently across approved training providers worldwide. Always confirm with your specific employer or operator that the certification from your chosen provider meets their requirements, particularly if you are working under a specific regional regulatory framework.
How far in advance should I book the OPITO Helideck Assistant course before my offshore deployment?
It is generally advisable to book your HDA course at least four to six weeks before your planned offshore deployment, both to secure a place on a suitable course date and to allow time for any administrative processing of your certificate. Booking earlier also gives you a buffer in case of unexpected scheduling changes on either side. If your deployment date is fixed and non-negotiable, choosing a training provider that offers guaranteed course dates and flexible rescheduling policies, such as free cancellation up to 24 hours before the start, can significantly reduce the risk of a last-minute disruption.
What should I bring or prepare before attending the Helideck Assistant course?
Most training providers will send a joining instructions document ahead of the course that outlines exactly what to bring, but as a general rule you should arrive with valid photo identification, proof of any prerequisite medical certificates, and any relevant employer documentation confirming your role. Wear comfortable clothing suitable for physical activity, as the practical exercises are hands-on and can be physically demanding. Getting a good night's rest before each day of training is also genuinely useful, as the course is intensive and requires active participation throughout.
